SyncLane for AI chats is a browser extension that works together with the SyncLane macOS app.
On gemini.google.com and chatgpt.com, it reads the conversation shown on the page (your messages and the AI's text replies).
Only to the SyncLane app running on the same computer, at http://127.0.0.1:47821. It does not send anything to the developer, to any server on the internet, or to any third party.
It has no account, no analytics, no advertising, and no tracking. It does not sell or share data. It does not use remote code.
The extension itself stores nothing. The conversation is saved by the SyncLane app, in a database on your own Mac. If the app is not running, the extension keeps the conversation in memory only until the page is closed, and sends it again when the app starts.
Remove the extension in Chrome (chrome://extensions) to stop everything. Delete the conversations in the SyncLane app to remove saved data.
